My Sony SA-WM40 subwoofer has power, but sound kicks out. I'll turn off power for about 5min and when turn power on, sound is back. Is something overheating?

My Subwoofer Sony SA_WM500 was always burn the fuse therefore I had to change the STK, but now it takes off sound very low, How can I have back the high sound level? Zaruque Quimuenhe


It's no clear what you mean by "I had to change the STK", but if that means you have somehow defeated the fusing or place a larger fuse than it requires then STOP and shut it off. You might be risking a fire or more serious damage to the amp.

I would recommend you find a hands-on tech to look at it.

If you have resolved the fuse problem and now just have low subwoofer volume, you might want to track it back to the source and ITS subwoofer volume setting. There IS a volume level control on the sub, too. Turn it up.

The manual is here:

My sa-ma40kicks off after it plays for a few minutes


This sounds like a power supply problem. If it works after is sits or cools, check at the power supply for bad or disturbed solder connections, a lot of time if you look at the circuit board where the component comes through you will see a small ring in the middle of the solder.

Sony SW no sound


does this sub have an LFE output? if so, connect that to the LFE input on the reciever and make sure it is set up properly in the set up menu in speaker configuration. if the sub has speaker line input outputs, connect speakers to input of sub and out of sub to amp/recvr

The speaker is starting to buzz during the low


It probably buzzes all the time, you just notice it when it is outputting little volume. Check the cables for loose connections or replace them with other cable as a test.

Bad output IC or voltage rectifier are the most likely at fault.

The switching power supply transistors have shorted out. Other parts may be gone also. A difficult fix. Too bad, it's a great sub.
